Pressure Ratings

Series 5000 piston accumulators are rated at minimum 4 to 1 design factors. For pressures over 5000 psi, please consult our applications specialist.

Fluids

Parker’s piston accumulators are compatible with a wide variety of fluids. Standard accumulators (with nitrile seals) may be used with petroleum-based industrial oils or water-based flame resistant fluids. Optional seals compatible with most industrial fluids are available with temperature ranges from -45°F to 325°F (-43°C to 162°C). 

Precharge

Units are shipped with a nominal nitrogen precharge as standard. For specific precharge pressures, specify at the time of order. 

Gas Valve

Series 5000 accumulators and gas bottles with 2” through 6” bores are supplied with a high pressure cored gas valve as standard. Models with 7” and 9” bores are supplied with a heavy duty (military) poppet-type gas valve cartridge (Mil. Spec. MS28889-2) as standard.
